我已阅读帖子:Fling gesture detection on grid layout并实施了手势检测。但我有以下问题。执行 onFling()操作后, onListItemClick()正在调用。如何解决这个问题?

你可以尝试
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
view.requestDisallowInterceptTouchEvent(true);
.....
view.requestDisallowInterceptTouchEvent(false);
}
也许有帮助

问题出在 onFling()方法中。如果操作成功完成,则此方法应返回true ,否则调用onClickItemClicked()
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2,
float velocityX, float velocityY) {
if (e2.getAction()!=MotionEvent.ACTION_UP){
return false;
}
try {
float diffAbs = Math.abs(e1.getY() - e2.getY());
float diff = e1.getX() - e2.getX();
if (diffAbs > SWIPE_MAX_OFF_PATH)
return false;
// Left swipe
if (diff > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
listener.onLeftSwipe();
// Right swipe
} else if (-diff > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
listener.onRightSwipe();
}
return true;
} catch (Exception e) {
}
return false;
}
